As you can see on php.net, the function is only included in PHP 5.2 and later. However, the comments section offers a working substitute.
I will modify it a bit to show how I made my customized version work.

if (!function_exists('array_fill_keys')) {
  function array_fill_keys (array $keys, $value) {
    return array_combine($keys,array_fill(0,count($keys),$value));
  }
}

Pasting the if block into all the files that call the function did the trick neatly enough for me, although probably you could just paste it once in the .module file. Note though that this only works for PHP 5 as the functions used in the replacement require at least that.
